Homework Statement
How strong an electric field is needed to accelerate electrons in a TV tube from rest to one-tenth the speed of light in a distance of 5.5
Homework Equations
I used uniform accel. forumla v^2=V_o_+2a(delta X)
v=3e7 (1/10th speed of light)
V_o_=Rest
m=9.11e-31(mass of eletron)
delta X= .055meters
all to find (a)
to find the Accelaration
and a=q/m(E)
The Attempt at a Solution
I need to find E i believe I came up with
a=2.72 m/s^2
and E= 3.98e-41 which was wrong...;/
Thankyou
